Q2 2022 HIGHLIGHTS

Oyu Tolgoi Underground Development Update

The Oyu Tolgoi project in Mongolia includes two separate land holdings: the Oyu Tolgoi mining licence, which is held by Entree's joint venture partner Oyu Tolgoi LLC ("OTLLC") and the Entree/Oyu Tolgoi joint venture property (the "Entree/Oyu Tolgoi JV Property"), which is a partnership between Entree and OTLLC. On August 4, 2022, OTLLC's 66% shareholder Turquoise Hill Resources Ltd. ("Turquoise Hill") provided an update on Oyu Tolgoi underground development:

COVID-19 cases identified at Oyu Tolgoi continued at low levels in the second quarter 2022 and the testing regime has been eased. OTLLC has continued to progressively increase on-site personnel numbers with the workforce in the second quarter 2022 approaching full capacity. OTLLC's major focus continues to be the safety and wellbeing of its workers. Ongoing monitoring of COVID-19 cases continues, and controls will continue to be reviewed, as necessary.

During the second quarter 2022, the underground project achieved a significant milestone with the blasting of the first two Panel 0 draw bells on the Oyu Tolgoi mining licence ahead of schedule. The third draw bell subsequently fired on July 29, 2022. The timing of sustainable production from Panel 0 on the Oyu Tolgoi mining licence is trending earlier in the first half 2023.

Underground production activities, including undercut blasting and on-footprint construction work such as roadways and steel set construction, continue to progress well. During the second quarter 2022, a total of 26,098 metres of undercut drilling, 2,071 metres of draw bell drilling and 8,061 square metres of undercut blasting were completed.

Turquoise Hill has completed its review of the 2022 cost and schedule update for the underground project. The 2022 cost and schedule update has resulted in an increase of the total expected underground development capital from $6.75 billion to $7.06 billion. The increase incorporates known and future incremental COVID-19 costs, escalation, associated taxes, and minor impacts of changes in labor laws.
